The measuring sonde of system adopts modes such as flange form, knot that can be undone by a pull formula, screw thread formula or locking clip formula to be installed in by mechanical connecting structure on the chamber or pipeline (as various flues) of tested process environment or process medium sample usually, the central analysis unit then generally be placed near the suitable instrument pulpit of the environment of a distance measuring sonde erecting stage or the instrument cabin built specially in.The cable that is used for providing power supply between central analysis unit and the measuring sonde and transmits signals such as the control of various systems, measurement is then by engineering construction standard the be laid in supporting structure set up between measuring sonde erecting stage and instrument pulpit or the instrument cabin such as crane span structure, groove box.Distance between measuring sonde erecting stage and instrument pulpit or the instrument cabin has several meters not wait to tens meters usually, there is the occasion that requirement of explosion proof is arranged for inflammable owing to having, the explosive material in zone, measuring sonde erecting stage, the central analysis unit is owing to include the various electronic devices and components and the circuit modules that may produce spark, generally need be placed on safety zone away from the measuring sonde erecting stage, distance between the two generally can be more longer, reaches hundreds of rice sometimes even go up km.
The central analysis unit is the brain of system, is used to carry out signal Processing, I/O and system operation management etc.The terminal of existing system generally is input/output device on the central analysis unit such as LCDs and keyboard or the terminal device such as the computer that are connected with the external data communication interface of central analysis unit, the terminal of system since the constraint of connection cable and volume more greatly, factor such as heavier normally can not or inconvenience be moved.
Because the measuring sonde and the central analysis unit of system are installed in the different location, and its terminal do not possess portable characteristics, and system exists a lot of inconvenience in operating aspect always, especially for installation, debugging and the maintenance of system.The installation of system, debugging and maintenance etc. operate in many times and need install and remove and debug systematic survey probe and installation mechanical connecting structure thereof in the measuring sonde erecting stage, and the terminal that output shows as measurement data is positioned at the place away from the scene, therefore the site operation personnel can not see immediately that its caused by operations changes, and has seriously reduced operating efficiency.For instance:
